Description
Technical field
What the present invention relates to is a kind of device of prosthetic arts, specifically a kind of artificial anal sphincter prosthese referring to button.
Background technology
Fecal incontinence is a kind of disease common clinically, and according to the sickness rate of statistics adult up to 2%, over-65s person sickness rate can reach 7%, and the sickness rate of in fact this disease is often underestimated because patient is ashamed of seeking medical advice.Fecal incontinence refers to that anal sphincter loses the control ability of discharging feces and gas, it easily causes multiple complications, not only bring considerable distress to patient, and bring many difficulties to nursery work, along with the development of aged tendency of population trend, fecal incontinence has become one of disease of urgent clinical needs solution.
Artificial anal sphincter prosthese effectively can control defecation, and help patient regains the control to oneself defecation, eliminates the psychological shade that anal incontinence is brought, and again sets up the confidence to life, improves the quality of life.The technology that artificial anal sphincter can bring glad tidings to patient as one, has extraordinary Prospect of R & D.
Through finding the literature search of prior art: U.S. Patent number: US7011622B2 and US8172745A1, disclose the artificial anal sphincter that a kind of Artificial Anal Sphincter(is used for the treatment of fecal incontinence), this technology is by PressureRegulating Ballon (pressure adjustment ball), Control Pump (control pump) and Cuff (clamp pouch) three parts compositions, control pump is the critical component of this artificial anal sphincter, its operation principle is that manual squeezing makes to carry out work, this shortcoming that this artificial anal sphincter is existed is: 1, the pressure of liquid bag type regulates asks the tissue fluid easily and in human body to permeate, thus cause the increase gradually of liquid capsule, the U.S. just has once had a routine patient to be forced to ABS to transplant out in body because pressure regulates the increase of ball liquid storage pouch, 2, patient manually must extrude control pump mode and the liquid in clamp pouch is drained into liquid storage pouch, and control pump is implanted to scrotum (man) or labia (female), impacts the life of patient.
Chinese patent literature CN102871773, publication date 2013-01-16, describe a kind of electromagnetic control type artificial anal sphincter device based on rectum perceptive function, this technology is by an electromagnetic control type actuator, two clamping plates drive mechanism is formed with arc close mechanism, by electromagnetic actuator to passing through drive mechanism, allow arc close mechanism tighten up and clamp intestinal, but the shortcoming of this mechanism is: 1, the shape of its actuator becomes triangular shape, it not a kind of ideal form of implanted prosthese, its wedge angle easily causes damage to other histoorgan in body, whether, when 2, circular arc actuator closes, due to the existence of two circular shape mechanisms, its clamped condition must have the space of a little round shape to exist, and differs and clamps intestinal completely surely, can effective stool control mode, still still to be tested.
In sum, although artificial anal sphincter system is the effective scheme for the treatment of severe fecal incontinence, the prosthese of water-bag type fails effectively to solve the problem of human body inner tissue liquid infiltration; The electromagnetic control type artificial anal sphincter apparatus design of rectum perceptive function is ingenious, but in planform with in structural design, is difficult to launch application clinically.
Summary of the invention
The present invention is directed to prior art above shortcomings, a kind of artificial anal sphincter prosthese referring to button is provided, is easy to miniaturization, light quality, be convenient to implant, improve the success rate of Using prosthesis.
The present invention is achieved by the following technical solutions, the present invention includes: some perpendicular straight arranged dactylus mechanisms and folding and unfolding actuator, wherein: dactylus mechanism is cirque structure and comprises some dactylus parts be rotationally connected successively, folding and unfolding actuator comprises: drive rope, two elevator wheels and micromachine, wherein: drive rope in turn through each dactylus part of dactylus mechanism, rope one end is driven to be fixed on end dactylus part, the other end is through the upper circular port arranged of elevator wheel, and be fixed on elevator wheel, two elevator wheels are connected with micromachine, the folding and unfolding driving rope is realized by elevator wheel, and then drive each dactylus part radially shrink or expand, realize the change of dactylus whole mechanism internal diameter.
Described driving rope is provided with two in each dactylus structure, is arranged at the both sides of dactylus part respectively, thus lays respectively at the internal side diameter of dactylus structure and outside diameter on the whole and correspondingly control contracting and control is put.
Two dactylus parts of the described head end being positioned at dactylus mechanism and tail end are taken turns with elevator respectively and are rotationally connected.
The structure of described dactylus part is: middle part is rectangular body, and front end and end are the connecting portion for being rotationally connected, and both sides are arrange the through wires hole driving rope.
Described connecting portion is the otic placode structure having through hole, and two otic placode structures of different dactylus part are connected by pin member respectively.
Described micromachine connects the pressure transducer of perception colonic pressure change.
The change of the pressure sensor senses colonic pressure that prosthese of the present invention is built-in, opens prosthese when needs defecation automatically by micromachine, controls prosthese and is opened to suitable degree, start defecation; Defecation completes, and when needing stool control mode, controls to close prosthese to appropriate level, realizes stool control mode.
Mechanism of the present invention is simple, and system compact, quality are light, and be convenient to improve transplanting succeed rate, after transplanting, the impact of system on patient is little, without the need to the manual stool control mode of patient, realizes defecation stool control mode by the control box of outside with panel communication in body, the rate of minimizing postoperative infection; The liquid storage pouch and the in-vivo tissue liquid that successfully solve water-bag type prosthese permeate problem of expanding; Implant simple, need not the complicated operations such as anastomosis of rectum be carried out, relieve patient ' s burden.
